Having never fixed a fridge before, I did a little research. The unit was not old & the cooling system was operating. Observing the frozen ice inside, I diagnosed it as the heat rod and/or it's thermostat as bad. I contacted ApplianceParts Pros, who assisted in confirming my theory. IMPORTANT NOTE: the sales advisor Joyce was truly an intelligent, knowledgable professional, NOT some "burger-order taker" usually encountered. This alone speaks VOLUMES. Subsequently, the parts arrived promptly,THEY WERE EXACTLY THE CORRECT PARTS, and I did the repair, saving myself time, money & inconvenience. I cannot, I repeat, cannot offer enough praise for ApplanceParts Pros. and will certainly recommend, & use if need be, going forward. Highly recommend !
